TERMINATE/SUSPEND Job with Checkpoint
URL: https://github.com/apache/flink/pull/8617#issuecomment-506202631
 
 
   In my opinion, If the checkpoint is timeout,  this checkpoint will be 
discarded. But the checkpoint coordinator would handle such abortion as usual 
and assume that the Flink job continues running. In fact, it looks like 
"running", but it doesn't process any records. In sync-checkpoint case, every 
task will be blocked after triggering the checkpoint. Unlocking only happens 
either when the task is cancelled or when the corresponding checkpoint is 
acknowledged. I guess stop-with-savepoint may have the same issue. I'm not sure 
if it will truly happen.
